The-object of the present invention is t0-l provide a double sllding window withoutj `counter-weights havin wedge-shaped joints, the sash frames of w ich are connected to 5 one another by means of ropes passing over which also the ropesare fastened which, contraryto the present practice, are passed not 1 only in an upwardbut also in a downward direction over upper and lower rollers respectively and whose ends are attachedto the bearln on which the outer sliding sash frame 1s pivotall mounted, the sliding sash frames may be xed. in their closed .or an intermediate position by means of a window board which may be moved at a right angle to and within the sides of the window frame,

Another feature of the invention lies in the special arran ement of the wedge-shaped members on tge inner longitudinalsurfaces lof the sliding sash frames for the purpose of tightening the window. v

The annexed drawings show, by Way of example, one embodiment of the invention. In

these drawings 1 8o Figure v1 is a longitudinal sectionof the position). v

Figure 2 isa longitudinal section of the sliding' window with the sashes intilted position. -v vFigure 3 is a cross section ofthe window frame and the .sash-frame at a point intermediate the transom and window board. Figure jis' a cross section of the window ,0 'frame at a point below the window board.

The lower edge ofthe inner sliding sash frame v2 isl pivotally connected to an end board 29 movable in vertical direction with-` lin the sides 6 of the window frame.A To

partly lopened sliding window (ventilating this end-board 29 also' the ropes 37 are fasdirection and have their ends attached to the lo bearings 39 of the outer sliding sash frame 3.

:'-claim 1, characterized by the p wedge-shaped lelements carried By this arrangement the outer sliding frame 3 in closing the window is sash posltivel vpulled into its closed position and oth alici f ing sash frames may be tilted without difiiculty. l Y

In order to Vget the parts of the window tightly fitting also in lateral direction, parwindow the said-wedges are brought into overlaying en agement, thus forcingthe outer sliding sas frame 3'rmly upon its re batement.

By means of the window board 33 which may be moved at a right angle to and with-v in the sides 6 of the window frame the 70 sliding sash frames are bein fixed in-ftheir closed as well as any interme late position by means of suitable stops. The window board 33in its closing position is in-tight engage-v ment with the lower edge of the end-board 29 forming at the. same time a support for the sliding sash frame 2 thus saving the ropes.

What I claim is:

1. In a double sliding window, a window frame having side ortions, inner and outer 30 sash frames, an en -board slidably mounted in the 'sides of the window frame and pivotally mounting the inner sash frame, a bearing pivotally mounting the outer sash frame, a rope connectingthe inner and outer sash frames,l and pul eys arranged above and below saidframes supporting said rope, and a window board mounted in the window 4frame for movement perpendicularly to the sliding movement of the sash frames for retaining the latter in adjusted positions.

2. A. window construction as-'claimed inf rovision of y the inner and louter sash frames midway the height of the'latter adapted to mutually engage one another when thesash frames are moved to closed position. In testimony whereof I aix my si ature.
